Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Participants with ingrown toenails (IGTN) were recruited to this study and compared with control participants with no history of ingrown toenails.
The inclusion criteria for the IGTN group were: (1) history of ingrown toenails on hallux within 1 year and (2) dorso-plantar standing view of foot x-ray taken or to be taken.
The exclusion criteria for the IGTN group were: (1) paediatrics (Age\<18), (2) pincer nails / fungal nails, (3) prior existence of osteoarticular surgery in the foot, (4) severe trauma that changes foot morphology, (5) uncontrolled systemic disease, (6) pre-existing neurological diseases and (7) lower limb paralysis or paresis.
The inclusion criterion for the control group was dorso-plantar standing view of foot x-ray taken or to be taken.
The exclusion criteria for the control group were: (1) all the exclusion criteria of IGTN group, (2) history of IGTN in his or her lifetime and (3) flatfoot / first metatarsophalangeal joint pathology as the chief complaint.
The symptomatic foot (or the more symptomatic foot in the case of bilateral involvement) in the IGTN group was examined. The left or right foot of the control group was randomly selected such that the ratio of the left or the right foot in the IGTN and control group was the same.
Their foot posture index-6 components, Staheli's index, radiological hallux valgus angle and active maximum dorsiflexion of the first metatarsophalangeal joint on weight-bearing were measured and compared.
For dependent variables with significant correlation, a one-way multivariate analysis of variance (MANOVA) was carried out to determine if there was a significant difference on the combined dependent variables. For dependent variables without significant correlation, separate independent sample t-tests / welch t-tests were performed.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The active maximum dorsiflexion of the first metatarsophalangeal joint was measured with goniometer on weight-bearing. The bisection was carried out under a weight-bearing condition to avoid error due to soft-tissue movement when participants changed from a non weight-bearing position to a weight-bearing position.
